android自定义省略号,android – TextView：在省略号后添加文本或更改省略号字符

试试这种方式

创建这个功能

public void makeTextViewResizable(final TextView tv, final int maxLine, final String expandText) {

if (tv.getTag() == null) {

tv.setTag(tv.getText());

}

ViewTreeObserver vto = tv.getViewTreeObserver();

vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

@SuppressWarnings("deprecation")

@Override

public void onGlobalLayout() {

ViewTreeObserver obs = tv.getViewTreeObserver();

obs.removeGlobalOnLayoutListener(this);

if (maxLine <= 0) {

int lineEndIndex = tv.getLayout().getLineEnd(0);

String text = tv.getText().subSequence(0, lineEndIndex - expandText.length() + 1) + " " + expandText;

tv.setText(text);

} else if (tv.getLineCount() >= maxLine) {

int lineEndIndex = tv.getLayout().getLineEnd(maxLine - 1);

String text = tv.getText().subSequence(0, lineEndIndex - expandText.length() + 1) + " " + expandText;

tv.setText(text);

}

}

});

}

如何使用

这将在第4行末尾写入“SeeMore”而不是“……”

makeTextViewResizable(tv, 4, "SeeMore");

现在不需要在xml中写这些行

android:ellipsize="end"

android:maxLines="3"
